At SigmaVoIP we understand that our clients would rather concentrate on their business rather than dealing with uber-technical jargon and cryptic interfaces. Harnessing the power of the latest technologies while making them easy to use is our ultimate goal.

Our choices of hardware and software are based on extensive research, testing and customer feedback. Our backend operations is our playground.
With an extensive experience in networking technologies, it comes natural to us to deploy and overbuild our own infrastructure to accommodate the most demanding of usage. At present, we have direct fiber optic interconnections with 37 major carriers and we employ exclusively the highest performing and dependable routing and switching equipment. We have several levels of redundancy at every juncture and we monitor our network performance around the clock. Our peered carriers are under the greatest of pressure to ensure that they too deliver to us their best performance.
